日全食景观: 从偏食到钻石环

A Total Solar Eclipse from Sliver to Ring

Explanation: This is how the Sun disappeared from the daytime sky last month. The featured time-lapse video was created from stills taken from Mountain View, Arkansas, USA on 2024 April 8. First, a small sliver of a normally spotted Sun went strangely dark. Within a few minutes, much of the background Sun was hidden behind the advancing foreground Moon. Within an hour, the only rays from the Sun passing the Moon appeared like a diamond ring. During totality, most of the surrounding sky went dark, making the bright pink prominences around the Sun’s edge stand out, and making the amazing corona appear to spread into the surrounding sky. The central view of the corona shows an accumulation of frames taken during complete totality. As the video ends, just a few minutes later, another diamond ring appeared — this time on the other side of the Moon. Within the next hour, the sky returned to normal.

说明: 这是上个月的太阳如何在白昼天空消失的过程。这部延时主题影片，则是建构自2024年4月8日摄于美国阿肯色州山景镇的多张照片。在影片开头时，一片片通常镶着黑子的太阳盘面，很奇怪的突然变暗。 而在数分钟内，大半的日盘就被不断前移的前景月盘给遮住了。然后在1小时之内，穿过月盘边缘的残存太阳光束，让月亮看起来像是一枚钻石环。在日全食期间，大部分的天空很幽暗，因此太阳边缘的明亮粉红日珥变得格外醒目，而日冕则看似蔓延伸展到周围的天空。以日冕为主题的中央影片，叠合自记录日全食阶段的多帧照片。在进入全食阶段的数分钟之后，于影片结尾时，月盘的反侧出现了另一枚钻石环。然后在接下来的1小时里，天空回复正常。
